There's some cool free templates at http://www.templatesbox.com/templates.htm I'm wondering, how much to pay a designer just to change some graphics (just text changes for the graphic)
If you get a layered PSD with the slices, it wouldn't be much at all to have someone change them around for you... maybe $3-$5 an image if you want someone to take a little extra time and do a good job.
If you don't have the sliced PSD, or a PSD at all - expect to pay a little more.
